Next-generation multi-model cloud database combining relational, document, graph, geospatial, and vector search in a single engine.

About SurrealDB

SurrealDB is an innovative, next-generation multi-model database engineered in Rust to drastically simplify modern application development. By combining the strengths of relational databases, document stores, graph databases, geospatial engines, and full-text/vector search into a single unified runtime, SurrealDB eliminates the necessity of maintaining multiple fragmented database systems.

The database features SurrealQL, an intuitive SQL-like query language that supports graph relation traversal, complex record links, and real-time live queries. Furthermore, SurrealDB can act as a direct backend for client applications: with fine-grained row-level permissions, token authentication, and WebSocket live updates, web and mobile apps can communicate directly with SurrealDB securely without custom backend API servers.

SurrealDB can run embedded in-memory, as a single local binary, in a distributed cloud cluster, or in the browser via WebAssembly. It is free and source-available for self-hosting, while Surreal Cloud offers a fully managed DBaaS with a free developer tier and scalable production tiers.
